When clean DNA is what you need, the DNeasy UltraClean Microbial Kit delivers, isolating high-quality genomic DNA from 1.8 ml of microbial culture. Beginning with a bead-beating protocol, cells are lysed through a combination of mechanical force, heat and detergent, vortexed using our specially designed adapter for the Vortex Genie 2 Vortex, bound to a silica spin filter and washed. The resulting DNA is recovered in a DNA-free Tris buffer.
